Pin Functions ILC7280

Pin Number Pin Name

Pin Description

1

VOUTA

Regulator Output A

2

GND

Ground

3

VOUTB

Regulator Output B

4

CNOISE (optional) Voltage Reference Bypass: Connect external 22pF capacitor to GND to minimize

output noise in regulator “A” or “B.” May be left open. Do not ground.

5

ENB

Enable/Shutdown B (input): CMOS compatible input. Logic high = enable, logic low or

open = shutdown. Do not leave floating.

6

VINB

Supply Input B (Internally connected to pin 8)*

7

ENA

Enable/Shutdown A (Input): CMOS compatible input. Logic high = enable, logic low or

open = shutdown. Do not leave floating.

8

VINA

Supply Input A (Internally connected to pin 6)* Galvanic connection only.

*If maximum current required from each regulator then connect both pin 6 and pin 8 to VDD
